ADAM TINDEL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO TINDEL- MORRIS COMPANY, OF EDDYSTONE, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

ANGULAR-BENDING IMACHINE.

SPECIFICATION forming part of Letters Patent No. 718,035, dated January 6, 1903.

Application filed April 26, 1902. Serial No. 104,779. (No model.)

To all whom i may concern: longitudinally confined to a cap-plate on Be it known that I, ADAM TINDEL, a citithecross-head, as shown in Fig. 3. zen of the United States, residing in Phila- In the operation of themachine, projections delphia,Pennsylvania,have invented certain upon the rod, bar, or shaft are clamped one 5 ImprovementsinTWisting-Machines,of which between the jaws 9 of the annular chuck and the following is a specification. another between the jaws 13 of the cross-head 5 5 The object of my invention is to provide a 12, and the chuck is then turned throughout simple and effective machine whereby a rod, such an are as to dispose the projections at bar, or shaft having thereon projections in the desired angle in respect to each other, the

IO the same longitudinal plane may be twisted intervening portion of the rod, bar, or shaft so as to cause said projections to project rabeing twisted accordingly, it being underdially from the shaft at anydesired angle in stood that the operation is performed while respect to each other. the rod, bar, or shaft is heated, so that such 'In the accompanying drawings, Figure 1 is twisting of the same can be readily effected.

15 a longitudinal section of amachine construct Supposing, for instance, that a shaft has four ed in accordance with my invention. Fig. 2 projections equidistantly disposed upon it is a transverse section on the line a a, Fig. l. longitudinally, all of these projections being Fig. 3 is a view, partly in elevation and partly in the same plane for convenience in forging, in transverse section, on the line b b, Fig. 1; and supposing that it is desired to dispose 20 and Fig. 4: is a longitudinal section illustratthese projections at angles of ninety degrees ing another machine embodying my invenin respect to each other upon the shaft, the tion. cross-head 12 will first be adjusted upon the Referring first to the machine shown in bed-plate or frame 1 so that its clamping- Figs. 1, 2, and 3, it will be noted that a suitjaws 13 will engage the second of the projec- 2 5 able bed-plate or frame 1 carries an annular tions on the shaft when the first or adjoining bearing 2 for a ring 3, and secured to or formprojection is engaged by the clamping-jaws 9 ing part of this ring is a worm-wheel 4, meshof the chuck. The projections being securely ing with a worm 5 on a transverse shaft 6, to held intheclampsahe chuck isturned throughwhich rotary movement may be imparted in out an arc of ninety degrees, whereupon the 30 any suitable manner. Across the front of clamps 9 and 13 are loosened and the shaft the lower portion of the ring 3 extends a Web is moved longitudinally and is at the same '7, and in the upper portion of this web are time turned one-quarter way around, so as to formed grooved guides for a pair of jaws 9, apply the second projection to the clampingthose portions of said jaws which are adapted jaws 9 and the third projection to the clamp 5 to the guides of the web 7 forming nuts for ingjaws 13, the first projection pass ing the reception of the threaded portions of a through the chuck. The projections being right-and-left screw 10, which is confined louproperly secured by the clamps, the chuck is gitudinally to a cap-plate 11 at one end of the again turned to the extent of ninety degrees web 7, whereby on turning said screw-shaft in the same direction as before, andthere is 0 the jaws 9 can be caused to move from and then a further longitudinal adjustment and toward each other. The ring 3, with its web partial turning of the shaft or bar, the third and jaws, thus constitutes an annular chuck and fourth projections being new applied, re-

; having an opening extending longitudinally spectively, to the clamps 9 and 13, and there through the same. Longitudinally adjustis then a final partial turn of the chuck, the

j 45 able upon the bedplate or frame 1 is a crossresult being that the successive projections head 12, the upper portion of which has guides will be disposed around the shaft at angles of similar to those of the Web 7 for a pair of jaws ninety degrees in respect to each other.

i 13, which can be moved from and toward each In the machine shown in Fig. 4 the parts of other by means of a right-and-left screw 14:, the machine shown in Figs. 1, 2, and 3 are combined with a second annular chuck comprising a ring 3 having clamping-jaws 9 and mounted in a bearing 2 which is longitudinally adjustable on the bed-plate 1 in the same manner as the cross-head 12 and carries worm-gearing 4 5"" for rotating the chuck.

In a machine of this character three projections may be simultaneously acted upon one by the clamp on the cross-head 12 and one by each of the clamps on the rotary chucks, the cross-head and one of the rotary chucks being adjusted longitudinally to suit the dis-' position of the projectionsor a machine may be constructed in accordance with my invention in which the two rotary chucks are employed without the intervening cross-head, one of said chucks being adjustable from and toward the other, or in machines which are intended for acting upon a uniform class of work such longitudinal adjustment of either of the clamping devices may be dispensed with.

Having thus described my invention, I claim and desire to secure by Letters Patcut-- 1. A twisting-machine in which are combined a chuck, a bearing in which said chuck can be operated, a clamping device carried by said chuck, a cross-head adjustable longitudinally from and toward the chuck, and clamping-jaws carried by said crosshead, said jaws having means whereby each may be moved parallel to the other and thereby hold central a piece operated upon, substantially as described.

2. The combination in a twisting-machine of achuck, consisting of a ring having a transverse web, a bearing engaging the external periphery of the chuck, with means for rotating said chuck, and a pair of clamping-jaws mounted on said web and provided with means whereby they may be moved toward or from each other, substantially as described.

3. The combination in atwisting-machine,

of an open-center chuck consisting of a ring having a web extending across it, a pair of jaws mounted upon said web and adjustable toward and from each other, a bearing for said chuck and means for rotating the chuck to any desired extent in said bearing, substantially as described.

4. The combination in a twisting-machine, of a pair of chucks, each provided with a clamping device and a bearing for each chuck in which it can be rotated to any desired ex tent, a worm-gear on one of the chucks and a worm for operating the same, one of said bearings being adjustable longitudinally toward and from the other and having means whereby it may be temporarily clamped in any desired position, substantially as described.

5. The combination in a twisting-machine, of a pair of chucks, each provided with a clamping device, a bearing for each chuck in which it can be rotated to any desired extent, and a clamping device located between the two chucks, said device having adjustable jaws and being movable longitudinally, substantially as described.

6. The combination in a twisting-machine, of a pair of chucks, each provided with a clamping device, a bearing for each of said chucks in which it can be rotated to any desired extent, a cross-head located between the two chucks and provided with clampingjaws, said cross-head and the bearing for one of the chucks being adjustable longitudinally from and toward the bearing for the other chuck, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ADAM TINDEL.
